| Vetor | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.6.3
Description
A race condition exists in the netlink dump function, allowing local users to cause a denial of service or possibly have other unspecified impacts by making sendmsg system calls with a crafted application. This leads to a double free operation associated with a new dump that started earlier than anticipated.
Recommendations
For Linux kernel versions prior to 4.6.3, update to version 4.6.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the netlink dump function to minimize the risk of exploitation.
